betta males are tropical fish they need alot of room to swim to make a big territory. from my past experience with betta males, they much PREFUR a 1-10 gallon tank rather then a container, cup, jar, or bowl. I am just giving some advise thats all. I bought a great habbitat for my male betta Bubbles a while ago it was 17$ and comes with a oxagen thing. Though bettas dont need to have bubbles throughout there tank like most tropical fish, they do like them. My betta mad a HUGE bubble nest out of his lol. ... and the tank is only 1.5-2.5 gallons. so ya its all good.
